DOE contract boosts Centrus’s HALEU goals as Urenco continues LEU expansion
In the latest twist in a long-term, multistep contracting arrangement with the Department of Energy, Centrus Energy has signed a contract to finalize terms of a $900 million DOE task order to expand production capacity for high-assay low-enriched uranium at its American Centrifuge Plant in Piketon, Ohio. The expansion is part of Centrus’s multibillion-dollar capacity expansion that also includes low-enriched uranium.
The new DOE award allows the company to transition its HALEU production cascade to a commercial-scale operation at Piketon. The contract also includes options for as much $170 million in HALEU purchases for DOE missions, for a total contract value of $1.07 billion. Those options are subject to the discretion of DOE.
